Identifying key items to be addressed by non-clinical operators to manage out-of-hours telephone triage services for older adults seeking non-urgent unplanned care in Belgium: an e-Delphi study.

BACKGROUND: This study aimed to achieve expert consensus regarding key items to be addressed by non-clinical operators using computer-software integrated medical dispatch protocols to manage out-of-hours telephone triage (OOH-TT) services for calls involving older adults seeking non-urgent unplanned care across Belgium. METHODS: A three-part classic e-Delphi study was conducted. A purposive sample of experts specialized in out-of-hours unplanned care and/or older persons across Belgium were recruited as panelists. Eligibility criteria included experts with at least 2 years of relevant experience. Level of consensus was defined to be reached when at least 70% of the panelists agreed or disagreed regarding the value of each item proposed within a survey for the top 10 most frequently used protocols for triaging older adults. Responses were analyzed over several rounds until expert consensus was found. Descriptive and thematic analyses were used to aggregate responses. RESULTS: N = 12 panelists agreed that several important missing protocol topics were not covered by the existing OOH-TT service. They also agreed about the nature of use (for the top 10 most frequently used protocols) but justified that some modifications should be made to keywords, interrogation questions, degree of urgency and/or flowcharts used for the algorithms to help operators gain better comprehensive understanding patient profiles, medical habits and history, level of support from informal caregivers, known comorbidities and frailty status. Furthermore, panelists also stressed the importance of considering feasibility in implementing protocols within the real-world setting and prioritizing the right type of training for operators which can facilitate the delivery of high-quality triage. Overall, consensus was found for nine of the top 10 most frequently used protocols for triaging older adults with no consensus found for the protocol on triaging patients unwell for no apparent reason. CONCLUSION: Our findings show that overall, a combination of patient related factors must be addressed to provide high quality triage for adults seeking non-urgent unplanned care over the telephone (in addition to age). However, further elements such as appropriate operator training and feasibility of implementing more population-specific protocols must also be considered. This study presents a useful step towards identifying key items which must be targeted within the larger scope of providing non-urgent out-of-hours telephone triage services for older adults seeking non-urgent unplanned care.

Design of a flow modulation device to facilitate individualized ventilation in a shared ventilator setup.

This study aims to resolve the unmet need for ventilator surge capacity by developing a prototype device that can alter patient-specific flow in a shared ventilator setup. The device is designed to deliver a predictable tidal volume (VT), requiring minimal additional monitoring and workload. The prototyped device was tested in an in vitro bench setup for its performance against the intended use and design criteria. The ventilation parameters: VT and airway pressures, and ventilation profiles: pressure, flow and volume were measured for different ventilator and device settings for a healthy and ARDS simulated lung pathology. We obtained VTs with a linear correlation with valve openings from 10 to 100% across set inspiratory pressures (IPs) of 20 to 30 cmH2O. Airway pressure varied with valve opening and lung elastance but did not exceed set IPs. Performance was consistent in both healthy and ARDS-simulated lung conditions. The ventilation profile diverged from traditional pressure-controlled profiles. We present the design a flow modulator to titrate VTs in a shared ventilator setup. Application of the flow modulator resulted in a characteristic flow profile that differs from pressure- or volume controlled ventilation. The development of the flow modulator enables further validation of the Individualized Shared Ventilation (ISV) technology with individualization of delivered VTs and the development of a clinical protocol facilitating its clinical use during a ventilator surge capacity problem.

A consensus statement on minimum operational standards for geriatric emergency care in Belgium: a modified Delphi study.

BACKGROUND: As emergency department (ED) leaders started integrating geriatric emergency guidelines on a facultative basis, important variations have emerged between EDs in care for older patients. The aim of this study was to establish a consensus on minimum operational standards for Geriatric ED care in Belgium. METHODS: A two-stage modified Delphi study was conducted. Twenty panellists were recruited from Dutch and French speaking regions in Belgium to join an interdisciplinary expert panel. In the first stage, an online survey was conducted to identify and define all possible elements of geriatric emergency care. In the second stage, an online survey and online expert panel meeting were organized consecutively to determine which elements should be recognized as minimum operational standards. RESULTS: Between March 2020 and February 2021, the expert panel developed a broad consensus including ten statements focusing on the target population, specific goals, availability of geriatric practitioners and quality assurance. Additionally, the expert panel also determined which protocols, materials and accommodation criteria should be available in conventional EDs (39 standards) and in observational EDs (57 standards). CONCLUSIONS: This study presents a consensus on minimum operational standards for geriatric emergency care in two ED types: the conventional ED and the observational ED. These findings may serve as a starting point towards broadly supported minimum standards of care stipulated by legislation in Belgium or other countries.

A survey on the availability of geriatric-friendly protocols, equipment and physical environment across emergency departments in Flanders, Belgium.

BACKGROUND: The acquisition of geriatric-friendly resources is an important part of adapting emergency department (ED) care to the needs of vulnerable older patients. The aim of this study was to explore the availability of geriatric-friendly protocols, equipment and physical environment criteria in EDs and to identify related improvement opportunities. METHODS: The head nurse of 63 EDs in Flanders and Brussels Capital Region was invited to complete a survey in collaboration with the chief physician of the ED. The questionnaire was inspired by the American College of Emergency Physicians Geriatric ED Accreditation Program and explored the availability, relevance and feasibility of geriatric-friendly protocols, equipment and physical environment. Descriptive analyses were performed. A region-wide improvement opportunity was defined as a resource that was never to occasionally (0-50%) available on Flemish EDs and was scored (rather or very) relevant by at least 75% of respondents. RESULTS: A total of 32 questionnaires were analysed. The response rate was 50.8%. All surveyed resources were available in at least one ED. Eighteen out of 52 resources (34.6%) were available in more than half of EDs. Ten region-wide improvement opportunities were identified. These comprised seven protocols and three physical environment characteristics: 1) a geriatric approach initiated from physical triage, 2) elder abuse, 3) discharge to residential facility, 4) frequent geriatric pathologies, 5) access to geriatric specific follow-up clinics, 6) medication reconciliation, 7) minimising 'nihil per os' designation, 8) a large-face, analogue clock in each patient room, 9) raised toilet seats and 10) non-slip floors. CONCLUSIONS: Currently available resources supporting optimal ED care for older patients in Flanders are very heterogeneous. Researchers, clinicians and policy makers need to define which geriatric-friendly protocols, equipment and physical environment criteria should become region-wide minimum operational standards. Findings of this study are relevant to facilitate the development process of this endeavour.

Structure and processes of emergency observation units with a geriatric focus: a scoping review.

BACKGROUND: Combining observation principles and geriatric care concepts is considered a promising strategy for risk-stratification of older patients with emergency care needs. We aimed to map the structure and processes of emergency observation units (EOUs) with a geriatric focus and explore to what extent the comprehensive geriatric assessment (CGA) approach was implemented in EOUs. METHODS: The revised scoping methodology framework of Arksey and O'Malley was applied. Manuscripts reporting on dedicated areas within hospitals for observation of older patients with emergency care needs were eligible for inclusion. Electronic database searches were performed in MEDLINE, EMBASE and CINAHL in combination with backward snowballing. Two researchers conducted data charting independently. Data-charting forms were developed and iteratively refined. Data inconsistencies were judged by a third researcher or discussed in the research team. Quality assessment was conducted with the Methodological Index for Non-Randomized Studies. RESULTS: Sixteen quantitative studies were included reporting on fifteen EOUs in seven countries across three continents. These units were located in the ED, immediately next to the ED or remote from the ED (i.e. hospital-based). All studies reported that staffing consisted of at least three healthcare professions. Observation duration varied between 4 and 72 h. Most studies focused on medical and functional assessment. Four studies reported to assess a patients' medical, functional, cognitive and social capabilities. If deemed necessary, post-discharge follow-up (e.g. community/primary care services and/or outpatient clinics) was provided in eleven studies. CONCLUSION: This scoping review documented that the structure and processes of EOUs with a geriatric focus are very heterogeneous and rarely cover all elements of CGA. Further research is necessary to determine how complex care principles of 'observation medicine' and 'CGA' can ideally be merged and successfully implemented in clinical care.

Co-location of out of hours primary care and emergency department in Belgium: patients' and physicians' view.

BACKGROUND: In Belgium, General Practitioner Cooperatives (GPC) aim to improve working conditions for unplanned care and to reduce the number of low acuity emergency visits. Although this system is well organized, the number of low acuity visits does not decrease. METHODS: We explored the view of patients and physicians on the co-location of a GPC and an emergency service for unplanned care. The study was carried out in a cross section design in primary and emergency care services and included patients and physicians. Main outcome measure was the view of patients and physician on co-location of a GPC and an emergency service. RESULTS: 404 patients and 488 physicians participated. 334 (82.7%) of all patients favoured a co-location. The major advantages were fast service (104, 25.7) and adequate referral (54, 13.4%). 237 (74%) of the GPs and 38 (95%) of the emergency physicians were in favour of a co-location. The major advantage was a more adequate referral of patients. 254 (79%) of the GPs and 23 (83%) of the emergency physicians believed that a co-location would lower the workload and waiting time and increase care quality (resp. 251 (78%), 224 (70%) and 37 (93%), 34 (85%). CONCLUSIONS: To close the expectation gap between GP's, emergency physicians and to reach for high care quality, information campaigns and development of workflows are indispensable for a successful implementation of a co-location of primary and emergency care.

Consistency of decision support software-integrated telephone triage and associated factors: a systematic review.

BACKGROUND: In the recent decades, the use of computerized decision support software (CDSS)-integrated telephone triage (TT) has become an important tool for managing rising healthcare demands and overcrowding in the emergency department. Though these services have generally been shown to be effective, large gaps in the literature exist with regards to the overall quality of these systems. In the current systematic review, we aim to document the consistency of decisions that are generated in CDSS-integrated TT. Furthermore, we also seek to map those factors in the literature that have been identified to have an impact on the consistency of generated triage decisions. METHODS: As part of the TRANS-SENIOR international training and research network, a systematic review of the literature was conducted in November 2019. PubMed, Web of Science, CENTRAL, and the CINAHL database were searched. Quantitative articles including a CDSS component and addressing consistency of triage decisions and/or factors associated with triage decisions were eligible for inclusion in the current review. Studies exploring the use of other types of digital support systems for triage (i.e. web chat, video conferencing) were excluded. Quality appraisal of included studies were performed independently by two authors using the Methodological Index for Non-Randomized Studies. RESULTS: From a total of 1551 records that were identified, 39 full-texts were assessed for eligibility and seven studies were included in the review. All of the studies (n = 7) identified as part of our search were observational and were based on nurse-led telephone triage. Scientific efforts investigating our first aim was very limited. In total, two articles were found to investigate the consistency of decisions that are generated in CDSS-integrated TT. Research efforts were targeted largely towards the second aim of our study-all of the included articles reported factors related to the operator- (n = 6), patient- (n = 1), and/or CDSS-integrated (n = 2) characteristics to have an influence on the consistency of CDSS-integrated TT decisions. CONCLUSION: To date, some efforts have been made to better understand how the use of CDSS-integrated TT systems may vary across settings. In general, however, the evidence-base surrounding this field of literature is largely inconclusive. Further evaluations must be prompted to better understand this area of research. PROTOCOL REGISTRATION: The protocol for this study is registered in the PROSPERO database (registration number: CRD42020146323).

Unplanned readmission prevention by a geriatric emergency network for transitional care (URGENT): a prospective before-after study.

BACKGROUND: URGENT is a comprehensive geriatric assessment (CGA) based nurse-led care model in the emergency department (ED) with geriatric follow-up after ED discharge aiming to prevent unplanned ED readmissions. METHODS: A quasi-experimental study (sequential design with two cohorts) was conducted in the ED of University Hospitals Leuven (Belgium). Dutch-speaking, community-dwelling ED patients aged 70 years or older were eligible for enrolment. Patients in the control cohort received usual care. Patient in the intervention cohort received the URGENT care model. A geriatric emergency nurse conducted CGA and interdisciplinary care planning among older patients identified as at risk for adverse events (e.g. unplanned ED readmission, functional decline) with the interRAI ED Screener© and clinical judgement of ED staff. Case manager follow-up was offered to at risk patients without hospitalization after index ED visit. For inpatients, geriatric follow-up was guaranteed on an acute geriatric ward or by the inpatient geriatric consultation team on a non-geriatric ward if considered necessary. Primary outcome was unplanned 90-day ED readmission. Secondary outcomes were ED length of stay (LOS), hospitalization rate, in-hospital LOS, 90-day higher level of care, 90-day functional decline and 90-day post-hospitalization mortality. RESULTS: Almost half of intervention patients (404/886 = 45.6%) were categorized at risk. These received on average seven advices. Adherence rate to advices on the ED, during hospitalization and in community care was 86.1, 74.6 and 34.1%, respectively. One out of four at risk patients without hospitalization after index ED visit accepted case manager follow-up. Unplanned ED readmission occurred in 170 of 768 (22.1%) control patients and in 205 of 857 (23.9%) intervention patients (p = .11). The intervention group had shorter ED LOS (12.7 h versus 19.1 h in the control group; p < .001), but higher rate of hospitalization (70.0% versus 67.0% in the control group; p = .003). CONCLUSIONS: The URGENT care model shortened ED LOS and increased the hospitalization rate, but did not prevent unplanned ED readmissions. A geriatric emergency nurse could improve in-hospital patient management, but failed to introduce substantial out-hospital case-management. TRIAL REGISTRATION: The protocol of this study was registered retrospectively with ISRCTN ( ISRCTN91449949 ; registered 20 June 2017).

Unplanned Readmission prevention by Geriatric Emergency Network for Transitional care (URGENT): protocol of a prospective single centre quasi-experimental study.

BACKGROUND: International guidelines recommend adapting the classic emergency department (ED) management model to the needs of older adults in order to ameliorate post-ED outcomes among this vulnerable group. To improve the care for older ED patients and especially prevent unplanned ED readmissions, the URGENT care model was developed. METHODS: The URGENT care model is a nurse-led, comprehensive geriatric assessment based care model in the ED with geriatric follow-up after ED discharge. A prospective single centre quasi-experimental study (sequential design with two cohorts) is used to evaluate its effectiveness on unplanned ED readmission compared to usual ED care. Secondary outcome measures are hospitalization rate, ED length of stay, in-hospital length of stay, higher level of care, functional decline and mortality. DISCUSSION: URGENT builds on previous research with adaptations tailored to the local context and addresses the needs of older patients in the ED with a special focus on transition of care. Although the selected approaches have been tested in other settings, evidence on this type of innovative care models in the ED setting is inconclusive. TRIAL REGISTRATION: The study protocol is registered retrospectively with ISRCTN ( ISRCTN91449949 ).

Geriatric support in the emergency department: a national survey in Belgium.

BACKGROUND: Older people in the emergency department (ED) represent a growing population and increasing proportion of the workload in the ED. This study investigated the support for frail older people in the ED, by exploring the collaboration between the geriatric services (GS) and the EDs in Belgian hospitals. METHODS: An electronic cross-sectional survey in all Belgian hospitals with an ED (n = 100) about care aspects, collaboration, education and infrastructure for older patients in the ED was collected. Descriptive analyses were performed at national level. RESULTS: Forty-nine of 100 surveys were completed by the GS. The heads of the ED returned only 12 incomplete questionnaires and these results are therefore not reported. Twenty-six of the 49 heads of GSs (53%) indicated that there was an agreement, mainly informal, between the geriatric and the emergency department concerning the management of older people on the ED. A geriatrician was available for specific problems, by phone or in person, in 96% of the EDs during daytime on weekdays. Almost all responding hospitals (96%) had an inpatient geriatric consultation team, of which 85% was available for specific problems at the ED, by phone or bedside during the daytime on weekdays. Twenty-nine heads of the GSs (59%) reported that older patients were screened at ED admission during the day to identify 'at risk' patients. The results of the screening were used in the context of further treatment (76%), to decide on hospital admission (27%), or to justify admission on a geriatric ward (55%). In the year preceding the survey, 25% of the responding hospitals had organised geriatric training for ED healthcare workers. Thirty-four heads of the GS (69%) felt that the infrastructure of the ED was insufficient to give high-quality care for older persons. CONCLUSION: Collaborations between EDs and GS are emerging in Belgium, but are currently rather limited and not yet sufficiently embedded in the ED care. Exploratory studies are necessary to identify how these collaborations can be improved.

Regional Cerebral Oximetry During Cardiopulmonary Resuscitation: Useful or Useless?

BACKGROUND: Approximately 375,000 people annually experience sudden cardiac arrest (CA) in Europe. Most patients who survive the initial hours and days after CA die of postanoxic brain damage. Current monitors, such as electrocardiography and end-tidal capnography, provide only indirect information about the condition of the brain during cardiopulmonary resuscitation (CPR). In contrast, cerebral near-infrared spectroscopy provides continuous, noninvasive, real-time information about brain oxygenation without the need for a pulsatile blood flow. It measures transcutaneous cerebral tissue oxygen saturation (rSO2). This information could supplement currently used monitors. Moreover, an evolution in rSO2 monitoring technology has made it easier to assess rSO2 in CA conditions. OBJECTIVE: We give an overview of the literature regarding rSO2 measurements during CPR and the current commercially available devices. We highlight the feasibility of cerebral saturation measurement during CPR, its role as a quality parameter of CPR, predictor of return of spontaneous circulation (ROSC) and neurologic outcome, and its monitoring function during transport. DISCUSSION: rSO2 is feasible in the setting of CA and has the potential to measure the quality of CPR, predict ROSC and neurologic outcome, and monitor post-CA patients during transport. CONCLUSION: The literature shows that rSO2 has the potential to serve multiple roles as a neuromonitoring tool during CPR and also to guide neuroprotective therapeutic strategies.

Characteristics of older adults admitted to the emergency department (ED) and their risk factors for ED readmission based on comprehensive geriatric assessment: a prospective cohort study.

BACKGROUND: Patients aged 75 years and older represent 12% of the overall emergency department (ED) population, and this proportion will increase over the next decades. Many of the discharged patients suffer an unplanned readmission in the immediate and midterm post-discharge period, suggesting under recognition of psychosocial, cognitive and medical problems. The aim of this study was to compare the characteristics of older patients admitted and discharged from the ED and to determine independent predictors for ED readmission 1 month and 3 months after ED discharge based on comprehensive geriatric assessment (CGA). METHODS: Cohort study in a Belgian university hospital. A CGA, including demographic and medical data (e.g. reason for admission, comorbidity, number of medications), functional (e.g. activities of daily living, falls), mental (i.e. cognition, dementia, delirium), and nutritional status, and pain, was performed in 442 ED patients aged 75 years or older. RESULTS: Patients discharged from the ED (n = 117, 26.5%) were significantly less dependent for ADL, mobility, shopping and finances compared with hospitalised patients. Hospitalised patients (n = 325, 73.5%) were significantly more at risk for having nutritional problems, had a higher comorbidity index, and a lower cognitive status compared with those discharged. Ninety-seven patients (82.9%) were discharged home from the ED. Of the latter, 18 (18.6%) and 28 patients (28.9%) suffered an ED readmission within 1 and 3 months, respectively. At one month post-discharge, nursing care at home, meals on wheels, and risk for depression; and at 3 months post-discharge previous hospitalisation in the last 3 months, physiotherapy and meals on wheels were found to be independent predictors for ED readmission, respectively. CONCLUSIONS: This study observed a geriatric risk profile in older adults at the ED and a high readmission rate of those discharged, and suggests the potential value of CGA in identifying older patients at high risk for ED readmission.

Evidence-based prehospital management of severe traumatic brain injury: a comparative analysis of current clinical practice guidelines.

OBJECTIVE: This study appraised the completeness and level of evidence behind prehospital recommendations in clinical practice guidelines (CPGs) for management of severe traumatic brain injury (TBI). Differences and similarities in key recommendations for prehospital emergency care were assessed between current CPGs. METHODS: A systematic search identified current evidence-based CPGs for the management of severe TBI. The identified CPGs were screened for prehospital recommendations. Finally, an evaluation of the completeness and level of evidence for each of the identified recommendations was carried out. A review of the literature identified additional evidence. Designs of the retrieved publications were considered and classified according to the GRADE levels of evidence. RESULTS: This study identified 12 current CPGs for the management of patients after traumatic brain injury. Of these, twenty-one prehospital recommendations were selected. Only a few CPGs made recommendations on temperature management and ventilation patterns. Statements on prehospital transport and advanced airway management were common to all of the guidelines. Statements on initial treatment demonstrated the greatest variability. The literature review identified several relevant publications not included in the CPGs even after we controlled for the indicated time-intervals of their literature search. In addition, evidence from more recent trials published outside the search-interval of the clinical practice guidelines was found. CONCLUSIONS: The use of current guidelines on traumatic brain injury will not always facilitate decisions about best or most appropriate practice for prehospital practitioners. The amount of recommended prehospital interventions varied considerably, and there was large content variation in prehospital recommendations in these guidelines. Not all evidence was taken into account and not all CPGs were up-to-date.

The swine flu emergency department: the relationship between media attention for the swine flu and registrations in an emergency medicine unit.

INTRODUCTION: When the world is faced with a new potential pandemic outbreak, the media report heavily about it. Media are an important disseminator of health threat information. This study examined potential media effects during the 2009 outbreak of A/H1N1 influenza. HYPOTHESIS: To examine the relationship between media reports of the swine flu and self-registrations in an emergency department (ED) of a tertiary hospital in Flanders, Belgium. METHODS: All articles concerning swine flu published in seven Flemish newspapers were selected during the biggest flu peak in Belgium. This number was compared with the number of patients who presented themselves with a self-diagnosis of swine flu symptoms during the same time frame. The Pearson's correlation coefficient was selected to determine the relationship. The cross-correlation function determined the direction of this relationship. RESULTS: A strong correlation was found between the number of potential patients (n = 308) and the number of articles in the Flemish press (n = 1657). The number of patients was the leading indicator; increases in the volume of written press followed increases in the number of patients. CONCLUSION: Media reporting is extensive when a new infectious disease breaks out and intensifies when it is feared that pandemic levels are reached. This was also the case with the swine flu outbreak in Flanders. These findings suggest that a rise in the number of media reports follows a rise in the number of cases, rather than the reverse.

Transition to suicide ideation and attempt among emergency room patients.

BACKGROUND: Suicidal thoughts and behaviours (STB) represent a persistent and serious public health problem, and suicide is among the leading causes of death worldwide. We focus on predictors of transition rates and time courses through the STB spectrum among psychiatric emergency room (PER) patients. AIMS: We aimed to investigate (a) whether currently suicidal patients had prior referrals to the PER, (b) for which reason they were previously referred to the PER and (c) the timing of this referral. METHOD: We performed a retrospective study spanning 20 years with 24 815 PER referrals. Descriptive statistics of patients' sociodemographic and clinical characteristics are provided and expressed as weighted proportions and means. Logistic regression was used to identify risk profiles of patients who had a higher chance of being referred for reasons of STB given their PER history. Multiple imputation and data weighting techniques were implemented. RESULTS: STB among PER patients was persistent and led to repeated referrals (up to five times more likely), often within a short period (18% <1 month). Those previously referred for ideation/plan had 66% higher risk of making the transition to suicide attempt, with 25% making this transition within a month after previous referral. This is similar to the transition from depressed mood to suicide ideation/plan. CONCLUSIONS: STBs in PER patients are persistent and lead to repeated referrals, often within a short period, including transitions to more severe forms of STB.

Changes in the use and uptake of a national out-of-hours telephone triage service by younger and older patients seeking non-urgent unplanned care surrounding the COVID-19 pandemic in Flanders (Belgium).

BACKGROUND: This study seeks to examine if and how the COVID-19 pandemic has prompted changes in the use and uptake of a national out-of-hours (OOH) telephone triage service by younger and older patients seeking non-urgent unplanned care in Flanders (Belgium). METHODS: A descriptive study was conducted using registry data obtained from the 1733 OOH telephone triage service in a Flemish region of Belgium. All calls received between 1 January 2019 and 31 December 2020 were analyzed. RESULTS: A significant association was found between patient age and period of call (χ2 = 594.54, p < .001). Calls made to the 1733 OOH telephone triage service were significantly less likely to be dispatched to a higher level of urgency by operators compared to calls made before the COVID-19 period (OR = 0.80, 95% CI [0.74-0.85]). While calls concerning older adults were significantly more likely to be dispatched to a higher level of urgency by operators compared to younger adults (regardless of period of call) (65 to 74 yrs: OR = 5.75, 95% CI [4.86-6.80]; 75 to 84 yrs: OR = 15.21, 95% CI [13.18-17.56]; ≥ 85 yrs: OR = 28.77, 95% CI [25.01-33.09]), only 6.7% of all COVID-19 related calls involved older adults over 65 years of age. CONCLUSION: Findings showed that there was a general decline in the number of calls dispatched to a higher level of urgency by operators during the COVID-19 period but that there were differences in the use and uptake of these services by younger and older age segments.

Can the heartscan be used for diagnosis and monitoring of emergencies in general practice?

INTRODUCTION: Mostly, it is impossible to establish the type of arrhythmias, based on signs and symptoms only. An ECG device is not always within reach. We presumed the heartscan, a handheld wireless device, to be of value to a GP in emergency situations. We therefore studied inter- and intra-observer variability and the accuracy of the screen readings. METHODS: All consecutive patients visiting the emergency department (ED) of the Gasthuisberg University Hospital in Leuven, Belgium, as well as patients hospitalised in three hospital wards on one day, were included. Immediately after the heartscan recording, a standard 12-lead ECG was recorded and read by an experienced hospital-based cardiologist. The recordings were read on the device screen by two general practitioners. All readers were blinded to the 12-lead ECG readings and vice versa, and for each other's ones. We compared both the heartscan reading of the first reader and the automatic reading of the device with the readings of the second GP and to the 12-lead ECG results, used as the gold standard. Intra- and inter-observer agreement was studied using total accuracy and kappa values with their 95% confidence interval (CI). RESULTS: Full data of 177 (73%) patients, 80 men (45%) and 97 women (55%), with a mean age of 55 years (range 18-94 y) were recorded. The specificity of the heartscan reading by a clinician was 88%, the sensitivity between 60 and 69%, PPV < 50% and NPV > 95%. Comparing codes of the heartscan with the ECG readings was difficult but sensitivity for atrial fibrillation was 92.3%. Inter- and intra-observer accuracy were high (> 0.86 and > or = 0.95, respectively), with low kappa values. CONCLUSION: The detection of rhythm disorders by the device is incomplete. However, the heartscan can be a help for the GP. The performance of the heartscan could probably be improved by increasing screen resolution, but, in the future, more sophisticated heart monitors should become available. They should be small, light and affordable.

Did COVID-19 Change Emergency Department Admissions?

OBJECTIVE: This study aimed to describe the impact of the coronavirus disease (COVID-19) pandemic on emergency department (ED) admissions for urgent diagnoses. METHODS: From January 1, 2019, until December 31, 2020, patients older than 18 years who attended the ED at University Hospital of Leuven (UZ Leuven, Belgium) were included. Urgent diagnoses selected in the First Hour Quintet were collected. The periods of the pandemic waves in 2020 were analyzed and compared with the same time period in 2019. RESULTS: During the first wave of the pandemic, 16 075 patients attended the ED compared with 16 893 patients during the comparison period in 2019. The proportion of patients having one of the diagnoses of the First Hour Quintet was similar between the periods (4.4% vs 4.5%). During the second wave, 14 739 patients attended the ED compared with 18 704 patients during the same period in 2019; 5.6% of patients had a diagnosis of the First Hour Quintet compared with 4.3% of patients in the comparison period. CONCLUSION: This study showed a decrease in the number of patients attending the ED during the COVID-19 pandemic. Further studies are needed to determine for which conditions patients visited the ED less.

Pooled Urine Analysis at a Belgian Music Festival: Trends in Alcohol Consumption and Recreational Drug Use.

BACKGROUND: Recreational drug use has become more and more accepted in society. Availability and purity are rising and new psychoactive substances (NPS) are popping up.The aim of this study was to provide objective data on illicit drug use at a Belgian festival in order to report on arising trends. This may provide additional information to help develop preventive strategies. METHODS: A cross-sectional study took place during a music festival in the summer of 2019, where 43 samples of pooled urine were collected at four different locations and at different moments of the day. Analysis was performed using gas chromatography with a flame ionization detector (GC-FID) to determine ethanol concentrations. Drugs of abuse were quantified using liquid chromatography-tandem mass spectrometry. A qualitative analysis was performed using high-resolution mass spectrometry. RESULTS: Median ethanol concentration was 0.88g/L. Cocaine, 3,4-methylenedioxymethamphetamine (MDMA), amphetamines, ketamine, and cannabis were detected in almost every sample and often in high concentrations. Furthermore, two NPS were detected and a variety of over-the-counter medication and adulterants were also found. DISCUSSION: The findings were largely in-line with trends outlined in the European Drug Report. Striking were the relatively high concentrations of MDMA and ketamine and detection of two synthetic cathinones. Two possible adulterants of cocaine were detected, namely flecainide and amlodipine. CONCLUSION: Music festivals are considered a high-risk setting for alcohol consumption and illicit drug use. Analysis of pooled urine samples at a festival therefore provides a valuable method to evaluate trends and to screen for new substances. Wide-spread use of classical drugs and identification of two NPS were observed during a major international music festival in Belgium. Results need to be interpreted carefully, taking into account the possibilities and limitations of the used techniques and a standardized sampling is required.

The Incident Management Response of the Emergency Departments in Belgium During the First Wave of the COVID-19 Pandemic.

The COVID-19 pandemic has demonstrated that emergency departments (EDs) need to reorganize their operations rapidly. This study investigated the impact of the pandemic on structural and logistical issues at EDs and the measures taken. Belgian EDs were surveyed on the implemented changes at the start of the pandemic in relation to the 4 S's in disaster medicine: Structure, Staff, Supplies, and System. The study demonstrated that Belgian EDs felt largely unprepared for this pandemic, but nevertheless dynamically restructured their organization. A 46% increase in ED beds was created in different types of structures and more than 50% of all ED beds were reserved for COVID-19 care, but overall the number of patient presentations dropped by 29%. EDs deployed extra personnel, additional training, and psychological support. More than 50% reported an acute shortage of personal protective equipment, and several reported a shortage of ventilatory equipment and medications.
